CompTIA Security+ Question K-72

A. File level encryption with alphanumeric passwords
B. Biometric authentication and cloud storage
C. Whole disk encryption with two-factor authentication
D. BIOS passwords and two-factor authentication

Answer: C

Whole-disk encryption only provides reasonable protection when the system is fully powered off. to make the most of the defensive strength of whole-disk encryption, a long, complex passphrase should be used to unlock the system on bootup. Combining whole-disk encryption with two factor authentication would further increase protection.
